This commit adds functionality to customize access logging format in

format is combined format.

Tatsuhiro Tsujikawa ce71e65aee nghttpx: Replace WARNING with WARN for consistency 2014-11-08 10:51:56 +09:00
Tatsuhiro Tsujikawa 31528b6267 Use uint32_t for HTTP/2 error_code
h2-14 now allows extensions to define new error codes.  To allow
application callback to access such error codes, we uses uint32_t as
error_code type for structs and function parameters.  Previously we
treated unknown error code as INTERNAL_ERROR, but this change removes
this and unknown error code is passed to application callback as is.

Tatsuhiro Tsujikawa d5dcbf6f3b nghttpx: Fix possible flow control issue
Previously we only update consumed flow control window when number of
bytes read in nghttp2 and spdylay callback is 0.  Now we notify
nghttp2 library the consumed bytes even if number of bytes read > 0.
This change also uses newly added spdylay_session_consume() API, so we
require spdylay >= 1.3.0.

Tatsuhiro Tsujikawa 93ed89df5f nghttpx: Make stream timeout disable by default
It might be useful to clean the unused stream out to make up the room
for new streams.  On the other hand, proxy should maintain the
connection between upstream client and downstream server and they have
the timeout for their own.  Proxy just reacts to their decision.

Tatsuhiro Tsujikawa 079db14d45 Add nghttp2_session_consume() API
Reworked no automatic WINDOW_UPDATE feature.  We added new API
nghttp2_session_consume() which tells the library how many bytes are
consumed by the application.  Instead of submitting WINDOW_UPDATE by
the application, the library is now responsible to submit
WINDOW_UPDATE based on consumed bytes.  This is more reliable method,
since it enables us to properly send WINDOW_UPDATE for stream and
connection individually.  The previous implementation of nghttpx had
broken connection window management.

Tatsuhiro Tsujikawa af5fd2019d src: Remove 0x00 concatenation for headers
Now concatenating header values with 0x00 as delimiter is not
necessary because HPACK reference set is removed and the order of
header field fed into HPACK encoder is preserved when they are
decoded.

Tatsuhiro Tsujikawa 0ce848a611 nghttpx: Rewrite logging system
This change rewrites logging system of nghttpx.  Previously access log
and error log are written to stderr or syslog and there was no option
to change stderr to something else.  With this change, file path of
access log and error log can be configured separately and logging to
regular file is now added.  To support rotating log, if SIGUSR1 signal
is received by nghttpx, it closes the current log files and reopen it
with the same name.  The format of access log is changed and has same
look of apache's.  But not all columns are not supported yet.

Tatsuhiro Tsujikawa 0e4b3d435e Emit header name/value pair using callback functions
Now, in nghttp2_on_frame_recv_callback, nva and nvlen in
HEADERS and PUSH_PROMISE frames are always NULL and 0 respectively.
The header name/value pairs are emitted successive
nghttp2_on_header_callback functions. The end of header fields are
signaled with nghttp2_on_end_headers_callback function.

Since NGHTTP2_ERR_PAUSE for nghttp2_on_frame_recv_callback is
introduced to handle header block, it is now deprecated.
Instead, nghttp2_on_header_callback can be paused using
NGHTTP2_ERR_PAUSE.

Tatsuhiro Tsujikawa ccfa13cd5b nghttpx: Rewrite location header field
We thought that this kind of rewrite can be achieved by the configuration
of the backend severs, but in some configuration, however, it may get
complicated. So we decided to implement at least location rewrite in
nghttpx.

This commit also contains a fix to the bug which prevents the http2
backend request from concatenating header fields with the same value.

Tatsuhiro Tsujikawa 40347487c9 Don't sort headers in library code

Tatsuhiro Tsujikawa 7b3f57cef8 shrpx: Fix blocking upstream RST_STREAM and propagate REFUSED_STREAM
This change fixes upstream RST_STREAM is blocked until
SpdyUpstream::send() is called. Now downstream REFUSED_STREAM is
propagated to upstream client so that client can reset request.  The
RST_STREAM error code when downstream went wrong is changed from
CANCEL to INTERNAL_ERROR.

Tatsuhiro Tsujikawa 9ba19df813 shrpx: Add --spdy-bridge option
With --spdy-bridge option, it listens SPDY/HTTPS connections from

outstanding SpdyDownstreamConnection objects are added to SpdySession
and establishing connection to SPDY backend is failed.

Tatsuhiro Tsujikawa 026f4ca3a2 Add --client-mode option
With --client-mode option, shrpx now accepts unencrypted HTTP
connections and communicates with backend server in SPDY.  In short,
this is the "reversed" operation mode against normal mode.  This may
be useful for testing purpose because it can sit between HTTP client
and shrpx "normal" mode.
